LCD 16X04 Blue Display Backlight
This LCD 16X04 Blue Display Backlight is highly sought after. It utilizes the SPLC780 or S6A0069 display controller, making it a seamless fit for most microcontrollers in various applications. The widespread demand for this product guarantees ample availability of compatible libraries across all microcontroller platforms.
LCD modules are frequently used in many embedded projects due to their affordable cost, widespread availability, and user-friendly programming. These displays can often be seen in our everyday lives, such as at PCOs or on calculators. As we have already discussed the design and pinouts previously, let us now delve into some technical details.
The LCD display has a 16×4 resolution, allowing for 16 characters per line across 4 lines.
This LCD is a well-known 16×4 version that features a Blue Backlight. It relies on the SPLC780 or S6A0069 display controller, allowing for a simple interface with most microcontrollers in various applications.
The widespread demand for this LCD guarantees that it is compatible with all micro controller platforms. It operates at a voltage of 5v and has a blue backlight that can be turned on or off according to preference. Additionally, the contrast of the screen can be easily adjusted by altering the voltage at pin 15, designated as the contrast control pin.
The LCD 16X04 Blue Display Backlight is named because it has 16 columns and 2 couple of rows. There are various combinations available, such as 8×1, 8×2, 10×2, and 16×1, but the most commonly used one is the 16×4 LCD. This type of LCD has a total of (16×4=64) 64 characters, with each character containing (5×8=40) 40 pixels. In total, there are (64×40) 2560 pixels on the screen. Additionally, the LCD must be given instructions for the positioning of these pixels. To simplify this process, an Interface IC like HD44780is is used. This IC is placed on the back of the LCD Module and handles commands and data from the MCU to display meaningful information on the screen. If you have advanced programming skills and want to create your own library for interfacing with this LCD module, you will need to refer to its datasheet to understand its functioning and commands.
